摘要
为了提高汽车轮胎压力检测系统(TPMS)无线通讯的可靠性,降低数据存储空间,提出了一种求取数据帧CRC(循环冗余码校验)校验码的半字节快速查表法,给出了实现该方法的过程,克服了单字节快速查表法占用存储空间大的缺点.试验结果表明,该方法的检错率可达99.9%以上,可以在TPMS中实际应用.
This paper proposes a half-byte rapid table-lookup method of CRC （Cyclic Redundancy Code） calculation to improve the reliability and reduce the memory space of wireless communication in Tire Pressure Monitoring System （TPMS）. The implementation of this method is presented, and it overcomes the disadvantage of the single-byte table-lookup method spending much more space for memory resource. It is shown by experiments that the error-checking rate of this algorithm can reach 99. 9 percent, and this method is applicable in TPMS.
